Hi, I have a blocked paved drive. I think it was laid around 15 years ago, I have been in the property for nearly 13 years. I had noticed a couple of loose bricks it looked like they had sunk. I have managed to look under one without completely removing it. There is a gap between the paving and floor of at least 10cms. I did not expect that and I know it can't be good. Very concerned about what is under the rest of the drive. What could have caused
this ? What would be the best cause of action to take ? Any advice would be appreciated.
